要分大、小調,首先要知道佢地o既音階排列。major scale係由d r m f s l t 組成,而minor scale係由 l t d r m f s l (natural minor)組成。所以要知道relative major/minor,首先要搵到 d 同 l 音。eg. G major, G 音係"d" ,要搵佢個 " l" 音,因為minor scale係由 "l" 音開始,亦即係呢個音階o既名稱,亦即係搵佢低一個minor 3rd(d -> t, -> l, 係minor 3rd),G = d, F# = t, E = l,,"l"音係E位置,所以係E minor,換句話講,G major 同 E minor 係共用一個 key signature 所以佢地係relative major/minor o既關係。
major key同minor key o既關係可以參考以下個表︰
C major = A minor
Db major = Bb minor
D major = B minor
Eb major = C minor
E major = C# minor
F major = D minor
F# major = D# minor
G major = E minor
Ab major = F minor
A major = F#minor
Bb major = G minor
B major = G# minor
至於睇到一份樂譜點分佢係major定minor?假設中間冇轉調的話,樂曲最後用"l"音結尾,而中間"s"音經常變左做"se"音,又或者有時"f"音轉左做"fe"音,呢首樂曲就係minor key。
而major key結尾會用"d"音,而中間好少會出現#、b。
